20.500.12556/DKUM-70872 A method for predicting the deformation of swelling clay soils and designing shallow foundations that are subjected to uplifting Metoda napovedovanja deformacij nabrekljivih glinenih zemljin in oblikovanje plitvih temeljev, ki so podvrženi dviganju Swelling soils can be found in many parts of the world. The state of practice in this area has been changing over recent decades. The design of foundations for expansive soils is an impo rtant challenge facing engineers. The excessive damage is, in part, due to the lack of proper design, resulting in the need for better tools for practitioners in order to assess the impact of swelling soils in typical design applications. A correct measurement of the swelling pressure is required for an accurate prediction of the heave. A theoretical model is proposed to describe the swelling potential of clay soils on the basis of their characteristics obtained from oedometer tests. This paper describes analysis of the behavior of swelling soils when moistened under buildings and structures. The methods and principles currently used for the design of structure foundations on swelling soils involve important problems due to the non-uniform deformations of these soils when subjected to structural loads. The current study was conducted to compute the uplifting of shallow foundations on swelling soils considering the water-content change as well as the contact-pressure distribution under the footing. Nabrekljive zemljine je mogoče najti v mnogih delih sveta. Stanje prakse na tem področju se spreminja v zadnjih desetletjih. Projektiranje temeljev v nabrekljivih tleh predstavlja pomemben izziv za inženirje. Pretirana škoda nastane deloma zaradi pomanjkanja ustreznega načrtovanja, zaradi česar je potreba po boljših orodij za projektante, da bi se ocenil vpliv nabrekljivih tal v tipičnih projektnih situacijah. Za natančno napovedovanje dvigovanja tal je potrebno pravilno merjenje tlaka nabrekanja. Predlagan je teoretični model, s katerim je opisan potencial nabrekljivih glinenih tal, karakteristike glin so pridobljene iz edometrskih preizkusov. Prispevek opisuje analizo obnašanja nabrekljive zemljine pri povečani vlažnosti pod zgradbami in objekti. Metode in načela, ki se trenutno uporabljajo za oblikovanje konstrukcij temeljev na nabrekljivih zemljinah, so zaradi neenakomerne deformacije teh zemljin pri obremenitvah, problematična. Pričujoča študija je bila izvedena za izračun dviganja plitvih temeljev na nabrekljivih tleh, z upoštevanjem spremembe vlažnosti zemljine, kot tudi porazdelitve kontaktnih tlakov pod temelji. swelling soil swelling magnitude swelling pressure free-swell oedometer test loaded-swell oedometer test shallow foundations nabrekljiva zemljina velikost nabrekanja pritisk nabrekanja prosti edometrski preizkus nabrekanja obremenitveni edometrski preizkus nabrekanja plitvi temelji true false true Angleški jezik Slovenski jezik Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Univerze v Mariboru Znanstveno delo 2018-06-18 08:29:16 2018-06-18 08:30:01 2023-07-31 09:20:56 2019-07-11 18:22:41 2016 0 0 str. 65-75 št. 1 Letn. 13 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1854-0171 215987712 302909952 1854-0171 URN:SI:UM:DK:IMWTPPSU Acta_Geotechnica_Slovenica_2016_Mohamed,_Mekhti,_Abdelhamid_A_method_for_predicting_the_deformation_of_swelling_clay_soils_and_designing.pdf Acta_Geotechnica_Slovenica_2016_Mohamed,_Mekhti,_Abdelhamid_A_method_for_predicting_the_deformation_of_swelling_clay_soils_and_designing.pdf 1 3828D35F21767A6DCA42FA95632632C7 ad05abf02c30370009dc4b360e23535d0d1999cb9e36e0b4487365a1546dde37 0b917d69-7c10-11eb-bb7a-00155d0001ca 20.500.12556/dkum/d534cb5d-38ec-457d-a3f4-40fe8381881b https://dk.um.si/Dokument.php?lang=slv&id=125812 http://fgserver3.fg.um.si/journal-ags/2016-1/article-6.asp 1 https://dk.um.si/Dokument.php?lang=slv&id=125811 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Acta geotechnica Slovenica 0 0 0
